文摘:將多種資源（人工、材料、機械）的數量同時在神經網路計劃技術上實行數字化疊加，從而獲得多資源疊加的合成分佈，再利用神經網路計劃技術中各個工作的不同時差和資源數量，按收斂條件選擇最佳開工工作和開工時間，滿足多種資源在優化模式中按收斂條件進行最優分佈Firstly, in spherical coordinate system, the sovp formulation for the time - harmonic electromagnetic fields of the current dipole in conductive infinite - space is derived, using reciprocity theorem and transforming relations between special functions. then, selecting appropriate coordinate system, using superposition principle, the boundary - value problem of modified magnetic vector potential on the problem of a time - harmonic current dipole in spherical conductor is solved and analytical solution is obtained. finally, by means of the addition formulas of legendre polynomial and spherical harmonics function of degree n and order 1, the analytical solution in spherical coordinate system specially located is transformed into that in spherical coordinate system arbitrarily located
首先利用特殊函數間的轉化關系和互易定理推導得到了無限大導體空間中球坐標下時諧電流元電磁場的二階矢量位形式：然後利用疊加原理，選擇合適坐標系，求解了導體球中時諧電流元的修正磁矢量位邊值問題，得到了問題的解析解；最後依據不同坐標系下電磁場解的轉化原理，藉助勒讓德多項式和n次1階球諧函數的加法公式，將坐標系特殊安放時的電磁場解析解變換到坐標系一般安放時的解析解，給出了球內電場和球外磁場的並矢格林函數。By choosing non - hybrid dictionary, blocking artifacts of dct system can be avoided ultimately. the cost of coding motion information is reduced, so the visual quality of images at low bit - rates is improved. 4
而且，通過選擇非晶格結構的字典（原子函數之間允許重疊） ，從根本上避免了低速率dct系統帶來的方塊邊緣失真，增加估計的精度，減少對運動信息編碼耗費並提高在低速率下的視覺效果。The search space is divided into many small areas, and each area is given a certain pheromone value. according to the state transition rules, the artificial ants move to the next solution which is generated randomly or calculated by particle swarm optimization. local search strategy is also added into psaco so that the search speed and precision is enhanced
該演算法首先將連續對象定義域平均分成許多邊緣相互重疊的小區域，區域的稠密程度決定了演算法解的精度，每個區域賦予一定的信息素值;螞蟻根據狀態轉移規則在隨機生成的可行解與利用微粒群演算法得出的可行解之間選擇下一步要去的位置;引入局部尋優策略，加強近似最優解鄰域內的局部搜索，提高搜索速度和精度。The key to enhance the image quality is to separate the reflection that has high signal to noise ratio and the scope of stack can defined optimally by common - angle gathers
提高成像質量的關鍵是分離出信噪比高的反射波並與根據共角度道集選擇最佳的疊加范圍層。The improved algorithm has three steps : 1 ) estimating the statics ; 2 ) selecting the best coherent time window from the common - receiver - point stack profile for the coherent computation and calculating the statics ; 3 ) correcting the value of " statics " by the underground structures corresponding to the formation of the p waves
演算法可以分3步進行：估算靜校正量；在共接收點疊加剖面上選擇一個最優相千時窗進行相干運算，求取靜校正量；根據縱波對應層位的地下構造對相於結果進行校正。It has practical value to the parameter selections of fans in series and to the sureness of the scheme in the series arrangement
